41b80eeffd [compiler] Propagate liveness across suspends
Suspend points (inside generators and async functions) have slightly
funky semantics when it comes to liveness, as they save and restore a
chunk of the register file as-is. In particular, this means that
granular liveness information is lost, as it is assumed that all
registers in that chunk of the register file are live in a suspend.

Rather than marking that entire chunk of register as live/dead in
suspend/restore, we can instead pattern-match the set of bytecodes in a
suspend point, and propagate liveness across them. This tightens
liveness estimates, and could be used to optimize which values TurboFan
actually saves when suspending.

56fe24372c [wasm][streaming] Do not reject promise upon abort without reason
This is the V8 side change of crrev.com/c/876103.

Message:
It can happen that WebAssembly.compileStreaming gets aborted when we
are not allowed to execute JavaScript code, and therefore are also not
allowed to reject the promise returned by WebAssembly.compileStreaming.
This can happen e.g. when the Chrome tab gets refreshed, which aborts
all downloads.

With this CL we do not pass a reason to Abort if we are not allowed to
execute JavaScript code. On the V8 side we can check the reason passed
to Abort and do not reject the promise if there is no reason passed.

c509d025c7 [turbofan] Inline StringCharCodeAt like Crankshaft did.
This avoids the call to the StringCharCodeAt builtin from
within TurboFan optimized code and instead emits a loop
that does the character load. This (together with previously
reverted CL to the JSCallReducer) almost completely recovers
the performance regression caused when we shipped TurboFan.

Without untrusted code mitigations the benchmark goes from
580ms to roughly 490ms, and with the patch to the JSCallReducer
the time goes down to 280ms, which is very close to what we
had with Crankshaft.

This also renames the LoadFromString helper method in the
EffectControlLinearizer to LoadFromSeqString to make it
clear what it does.

b30330c968 [mips][turbofan] Pass the slot index for the Peek instruction by operand
This is the implementation of crrev.com/c/866721 for mips and mips64.

Drive-by change: I made the slot index calculation on mips the same as
on mips64.

Original description:

At the moment the slot index is encoded in the opcode. This, however,
sets an upper limit the slot index which is lower than what we want to
have (i.e. < 512). With this change we pass the slot index as an
immediate operand, which does not impose limits on the value it
contains.

e0e8431d92 [esnext] Implement String.prototype.{trimStart,trimEnd}
Until now, String.prototype.{trimLeft,trimRight} were non-standard
language extensions, required for Web compatibility.

The proposal at https://github.com/tc39/proposal-string-left-right-trim
standardizes this functionality as String.prototype.{trimStart,trimEnd},
and defines String.prototype.{trimLeft,trimRight} as aliases for
backwards compatibility.

This patch implements that proposal behind the --harmony-string-trimming
flag.
